Abstract

The utility model relates to an infrared long-distance alarm, which is composed of infrared probes, a control circuit, a radio emitter, and a power supply. The utility model is characterized in that the control circuit works by the infrared probes triggering, and controls the working state transition of two relays which are connected in the power supply loop of the radio emitter to achieve the goal of controlling the radio emitter to emit alarm signals. The device has the advantages that the circuit structure is simple; the device can reset after a trigger, etc.

Description

A kind of infrared ray long-distance alarm apparatus

The utility model relates to a kind of antitheft, fire prevention, the anti-infrared warning device of plundering.

Existing infra-red detection warning device is that wired mode is transmitted alerting signal mostly, therefore can't finish the function of remote alarms.What described infra-red detection warning device had just keeps alarm condition once trigger reporting to the police, and resetting needs by manually finishing, though have auto-reset function arranged, circuit design complicated again.

The purpose of this utility model is to provide a kind of have auto-reset function, the simple infrared ray long-distance alarm apparatus of circuit.

The utility model is made up of infrared probe, control circuit, wireless launcher and power supply; It is characterized in that: control circuit is made up of timing frequency divider IC2, IC3 and relay J 1, J2; Have infrared PIR to be connected to wherein between 2,4 pin of timing frequency divider IC2 and dc power cathode, timing frequency dividing circuit IC2 the 11st pin connects the base stage of triode 1BG1; Triode 1BG1 emitter connects 5 pin and the dc power cathode of timing frequency dividing circuit IC2, the normally opened contact 4 of collector connecting relay J1; The 1st, 3,14,16 pin of timing frequency divider IC2 are connected to the oscillation frequency circuit of resistance, electric capacity formation; When infrared probe PIR has signal output, the 11st pin output high level of timing frequency divider IC2, triode 1BG1 conducting, conducting between the normally opened contact 5,1 of relay J 1, described relay J 1 contact 5 connects dc power anode, and contact 1 connects the power end of wireless launcher Y and the 16th pin of another timing frequency divider IC3; The 3rd pin of timing frequency divider IC3 is connected with the base stage of another triode 1BG2, the emitter of triode 1BG2 is succeeded the contact 1 of electrical equipment J1, collector connects the contact 3 of another relay J 2, and the contact 5 of relay J 2 connects dc power cathode, and contact 2 connects another power end of transmitter; Between the 10th pin of IC3,11 pin, be connected to resistance R 11; When the contact 1,5 of relay J 1 was connected, timing frequency divider IC3 got electric, its 3rd pin along the time export noble potential, triode 1BG2 conducting, relay J 2, normally closed contact 2,5 disconnect the wireless launcher dead electricity.

The utlity model has circuit structure and simply, once trigger characteristics such as automatically reset.

The drawing explanation:

Fig. 1 is the circuit diagram of a kind of infrared ray long-distance alarm apparatus described in the utility model.

Principle of work of the present utility model is as follows:

Power to mu balanced circuit IC1, timing frequency divider IC2, IC3 and infrared probe PIR by direct current 12V power supply.Infrared probe is started by the dynamic induced signal of the person, and be sent to IC2 the 2nd pin, and trigger IC2 and work, at this moment, the 11st pin output high level, make triode reason 1BG1 conducting, make 5 and 1 normally opened contact conducting of relay J 1, because the normally opened contact of relay J 2 is connected between power cathode and transmitter power one end, thereby transmitter starts working, after 1,5 contacts of relay J 1 are switched on, IC2 simultaneously electric work, after delay time second through 3-4, IC3 the 3rd pin is exported a high level, makes triode 1BG2 conducting.Because triode 1BG2 conducting, the normally closed contact 2,5 of relay J 2 is disconnected, and the power supply other end of transmitter is cut off, and the transmitter dead electricity quits work.The resistance that between the 1st, 3,14,16 pin of above-mentioned IC2, is connected, the selection of capacitance parameter determines its 11st pin to be converted into to the time of electronegative potential by noble potential; Resistance R 11 decision IC3 the 2nd pin that connects between the 11st, 16 pin by IC3 is converted to the time of electronegative potential by noble potential.
